Specification of Letters Patent.

Patented uly 9, 1907.

Application filed December 31g 1906. Serial No. 350,169.

To all whom it may concern:

Be itknown that I, JOHN BANNrsTnR GIBSON, a citizen of the United States, residing yat Webster Groves, in the county of St. Louis and State of Missouri, have invented a new and useful Heating and Ventilating System, of which the following is a specification.

This invention relates to systems for heating, cooling and Ventilating passenger cars,`sleepingcars and other rail-way rolling stock and has for its object to provide means whereby the interior of the car maybe heated and thoroughly ventilated `in winter and maintained at a uniform cool temperature in summer.

A further object of the invention is to provide a plurality of air-passages or conduits extending the entire` length of the car and communicating with the interior of the latter by means .of suitable passages or tubes opening-through the walls of the several seats or berths whereby the air i: discharged at the floor of the car and thus permitted to circulate within the latter and thoroughly ventilate the car. l

A further object is to provide means for purifying the air preparatory to its admission to the interior of the car, and means for controlling the supply of air to said car.

' A still further object is to provide a combined heating and refrigerating apparatus operatively connected through the medium of suitable connecting pipes and valves so that ,by manipulating the several pipes either apparatus may be used when desired. I

Further objects and advantages will appear in the following description, it being understood that variousl changes in form, proportions and minor details of construction may be resorted to within the scope of thevappended claims.

In the accompanying drawings forming .a partof this specification; -Figure 1 is a vertical sectional View of the lwer portie of a ear constructed in accordance lwith my invention".A 2 is a longitudinal sectional view of the same. vis a similar view taken on the line 3-3 ofFig. 2. Fig. 4 .is a side elevation partly in section showing the construction of the heater and the arrangement of the connecting pipes and controlling'v valves.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved heating and cooling system is principally designed for installation in passenger cars orin Pullman and similar sleeping cars and by wayof illustration `ifs shown in connection with a passenger car of the ordinary construction in which 5 designates the o floor of the car'supported .by the'outer and intermediate longitudinal sills 6 and 7, and 8 the seats of any approved construction.

Arranged-beneath the ioor of the car andinterposed between the adjacent outside and intermediate longi- The refrigerating apparatus is connected to the paratu's.v I- Communication between the heating pipes in the 105 tudinal sills are troughs or conduits 9 and 9/preferably rectangular in cross-section and extending the entire length of the car, as shown. l The conduits 9 and 9/ are formed of metal or othei` suitable material and are each provided with an air chamber or compartment 10 which is intersected by a fan-box or casing 10 preferably disposed at the lcenter of the car, as indicated by dotted lines in Fig. 2 of the drawings. l

Arranged in a suitable compartment or locker l1 at one end of the car is the stove or'furnace 12 of an ordinary Baker car heating system, the heating pipes 13 of which extend within the chambers 10 of the conduits andare connected with the usual heating coils or worms le of the stove, thus thoroughly heating the interior of the car in winter. One terminal of the heating pipe within the conduit 9 is connected to a vertical pipe 15 communicating with one of the expansion drums 16 of the heating system while the opposite terminal of the heating pipe is connect? ed to a similar pipe 17 leading tothe adjacent coil or worm of the stove. The terminals of the heating pipes within the conduit 9 are connected to vertical pipes 18 and 19 leading to the opposite coil or Worm of the stove and the adjacent'expansiondrum 20, respectively, thus permitting 'ee circulation of the heating medium through the stove. and heating pipes of each conduit. l J

lArranged within a`compartment or locker 21 is-a f refrigerating apparatus 22 of any approved vconstruction and adapted tol be operatively connected with the heating pipeawhereby` the latter may be used for containing a refrigerant when it is desired to cool or reduce the temperature of the car, as will be more fully explained hereinafter.

heating pipes within the conduit 9 by means of branchpipes 23 and 24 each provided with a valve 25 whereby communication betweeny the refrigerating apparatus and. the'heating pipes 13 may be cut off.,` there being amain valve 26 arrangedin the heating v pipe between the valves 25 for controlling the now of brine or other refrigerant in said pipes when the rev frigerating apparatus. is in operation. f

The 'pipes 15 and 19 are also provided with suitable valves'27 While the'pipes 17 and 18 are provided with 1.0 0"

similar valves 28 so -that the coils or worms 14 mayv be disconnected from the heating pipes in the conduits; when it'is desired to use the refrigerating apconduits 9 and 9 is normally cut off by means of suitable valves 29 and preferably .disposed between j l the pipesl? andlS and the pipes 15 and 19, as best shown in 2 of the drawing, so that the Awater or other heating medium in the pipes 13 of each con 110 so` l init is free to circulate independently of the heating medium in the opposite conduit.`

When it is desired to use the heating apparatus the valves 25, 29 and 30 are closed and the valves 26,

5 27 and 28 moved to open position thus permittingl the heating medium' in the pipes of each conduit to flow from the expansion drumthrough .the conduit and Othence through the adjacent worm or coil 14 back to the expansion drum, as indicated by plain arrows in Fig. 2 of the drawing.

In order to use the refrigerating apparatus the valves 26, 27 and 28 are closed and the valves 2.5, 29 and 30 moved to open position thus permitting the refrigerant to flow through the branch pipe'23, valve 15 25 and Nthe pipes 13 in the-conduit 9 to the valve'- 13 in the conduitV 30 and thence through the pipes 9 to the valve 29 and back through the valve 25 in the branch pipe 24 to the refrigerating apparatus, as indicated by the feathered arrows in Fig. 2 of the draw- 2o ing.

It will thus be seen thatby manipulating the several valves the reirigerating and heating apparatus may be connected to and disconnected 4from the pipes 13 thus permitting either the heating or cooling` 25 apparatus to be used, as desired.

The pipe 31 is preferably arranged within the conduit 9 and connected at one end by a suitable valve to a storage'or supply tankgjthe opposite vend of vthe pipe being disposed between two of the heating or cooling pipes in the adjacent conduit andl operatively connected with a water cooler 32 provided with a suitable faucet whereby the water in the cooler may be kept cool in summer by reason of the'proximity of the pipe 31 to the refrigerating coils, or Vwarm,' in

winter by reason of the heating medium flowing through said coils. I 4

The lower walls of the conduits 9 and`l9 are preferv ably inclined towards the chambers or casings 10 so as to cause the water of condensation from the pipes 13,

when the latter are used for refrigerating purposes to flow towards the'fan-casing, saidwalls being slightly 'elevated or inclined upwardly, as indicated at 33 to form a dam'on each side of the fan casing and thus retard the flow of water.

The casing 10 extends below thelongitudinal plane of the adjacent conduit and arranged within the casing A are inclined plates corrugated transversely to form a series of steps 34 whichtend to retard and spread the water as the latter iio'ws over'the dams into the bottom 50 of the fan-box. Mounted for. rotation within each fan-- box is a shaft 35 carrying a fan 36, the -latter being rotated by a pulley 37 secured to the shaft 35 and operatively-connected with the axle of the car through the medium. of a belt, chain or similar device whereby 5 5 'motion may be imparted simultaneously to both fans.

Communicating with the/interior of the fan-boxes or casin'gs are suitable globe ventilators 38 through which air is admitted to the fans, the quantity of air admitted to said fans being regulated by a suitable slide valve or i mgeratng apparatus a heating apparatus a pluralityof pipes disposed one on each side of the car and operatively connected with the heating and refrigerating apparatus,

gate 39, as showna v Extending through the side walls of the car-seats 8 and communicating with the interior of the conduits 9 and 9 are suitable pipes or tubes 40 through which ythe air from the chambers 10 is discharged into the interior of the car, there being suitable screens 41 arranged at the mouth of each pipe to prevent the en tra'nce of dust or other foreign matter within the com` l 'partmenta It will thus be seen that when the refrigerating appa- -ratus is operatively connected with the -pipes in the conduits 9 and 9 and the fan 36 rotated the blast of air air from any foreign particles or other impurities, the

air being further cooled by coming in. contact with the frost incrusted pipes so that cool fresh air will be discharged through the'pipes 40 into `Jthe car at the bottom of the latter and thus circulate through out the same and thoroughly ventilato the car.

When the refrigerating apparatus is disconnected from the heatingapparatus and the latter used for heating lthe interior of the car, the fan 36 will accelerate the natural flow of hot air from the conduits 9 and 9 into the interior of the car'and thus thoroughly heat the same, as will be readily understood. If desired, however, the fan may be used when neither the heating or refrigerating apparatus is in use, in order to promote the circulation of air within the car.

The fan vboxes or casings 10 are preferably provided with suitable drip openings 42 to permit the escape of the water of condensation when the refrigerating apparatus is employed.

The conduits 9 and 9 are of sufiicient width and height to vaccommodate any electric light and power wires, battery boxes, gas and water pipes and other fixtures used' in connection with the car, there being a trap door 43 in the .floor of the car in order to obtain access to all water pipes, valves, electric cut out switches, gas valves, battery `boxes and the like so that the same may be readily controlled or repaired' when out of order by accident or otherwise.

It will of course be understoodthat a similar door may be arranged on both sides of the ca r if necessary in order that access may be obtained to the conduit\9". From the foregoing description it is thought that the construction and operation of the device will be readily vunderstood by those skilled in the art and' further de scription thereof is deemed unnecessary.
